Environmentally Friendly and Recyclable CuCl 2-Mediated C-S Bond Coupling Strategy Using DMEDA as Ligand, Base, and Solvent

Simple reaction conditions and recyclable reagents are crucial for environmentally friendly industrial applications. An environment-friendly, recyclable and economic strategy was developed to synthesize diaryl chalcogenides by the CuCl2-catalyzed C S bondformation reaction via iodobenzenes and benzenethiols/1,2-diphenyldisulfanes using N,N'-dimethylethane-1,2-diamine (DMEDA) as ligand, base, and solvent. For these reactions, especially the reactions of diiodobenzenes and aminobenzenethiols/disulfanediyldianilines, a range of substrates are compatible and give the corresponding products in good to excellent yields. Both of the reagents in the catalytic system (CuCl2/DMEDA) are inexpensive, conveniently separable, and recyclable for more than five cycles.

A simple, fast, and easy assay for transition metal-catalyzed coupling reactions using a paper-based colorimetric iodide sensor

A paper-based colorimetric iodide sensor (PBCIS) that consists of filter paper treated with starch and an oxidant is developed. It has been employed as a protocol to obtain the extent of conversion of aryl iodides in C-C, C-N, C-O and C-S bond formations, including polymer-supported Heck reactions, by transition metal catalysts such as palladium, nickel and copper.

Reaction of 4-Bromo-1,2-dimethylbenzene with Various Nucleophiles via Aryne Reaction

4-Bromo-1,2-dimethylbenzene (4a) reacts with a variety of amines, mercaptans, and nitriles under aryne-forming conditions to yield predominantly 4-substituted 1,2-dimethylbenzenes and minor quantities of 3-substituted 1,2-dimethylbenzenes.The product distributions from these reactions are heavily in favor of the 4-substituted isomer since it is formed exclusively from the symmetric 4,5-dimethylbenzyne intermediate (6) and partly from the unsymmetric 3,4-dimethylbenzyne intermediate (5).
